This invention. relates to, improvements in Y the buildingart and particularlyto a means forapplying and securing plaster board lathing or likelathing to metal studs in the erection of walls of various types for Class A buildings,*and is particularly directed towards a fasteningmeans and method in con---' nection with the manner of attaching lathing to the'studs as preferably set forth in the i Makowski Patent No. 1,579,377, although the present invention can well be directed also to the fastening of metal lathing to the metal studs, as will develop as this description is proceeded with.

The primary objective of the present inven- 7 tion is to produce a; method and fastening means for the purpose noted by which the lathing may be rapidly, efiectively and securely attached to the studding, working i solely from the front plane of the wall so that the entire mounting of the lathing may be accomplished with a minimum amount of expense of time, labor and material.

These objects we accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusual of the following specification and claims.

In the drawings similar characters of reference indicate corresponding parts in the several views Fig. 1 is a perspective view in section of a fragmentary portion ofa stud and piece of. plaster board lathing showing the fastening element in the position .it assumes when the several elements are all secured together.

Fig. 2 is. a. sectional view through the studding and lathing showing the fastening ele- V ment projecting into position ready for the fastening prongs to'be cinched together to secure the several parts firmly together.

Fig. 3 isa-view similar to Fig. 2 but showing the first bend of the prong made by the tool in carrying out the fastening ope-ration.

Fig. .4 is a view similar to Fig. 3 showing the next bend made in the prong and which completes the fastening operation.

Fig. 5 is a perspective view of the fastening element.

Fig. 6 is a perspective view of a fragmentary piece of studding and a piece of metal lathing showing a modified formor fastening element which can be used in connection with our improved method for fastening the metal lathing to the studding' Fig. 7 is a perspective view-of the type of fastening element shown inconnection with Fig.6. v

Fig. 8is a sectional view of a stud and fragmentary piece of metal lath showing a modified form of fastening element from that Shown in Figs. 6 and 7. 1 Referring now more particularly to the Characters of reference on the drawings, the numeral 1 denotes the studding which is of the usual channel shape, and the legs la of which have inclined inner surfaces 11). The numeral 2 designates the plaster board lath which forthe purpose of, carrying out our improved method is provided with a longitudinal slot 3 at various points in its width and lengthat which the lath is to be secured against the studding. In a greatmany cities ordinances provide that lathing of this type shall be secured to the 'studding at approximately everysix inches, and the lathing strips in I commercial manufacture usually run about six feet long and from twelve to eighteen incheswide and consequently there would be one of these slots 3 at approximately every six inches throughout the width of the 'lathing and at. spaced longitudinal intervals approximating the distance between the studs used in the erection of the wall. By this means the lathing could be applied to the studding as taught inthe Makowski patent above mentioned, and the length of the slots would be such as to at all times presenta slot transverselyacrossa stud to permit ofthe insertion and securing of the fastening element, which is constructed and applied substantially as will now appear.

The fastening element comprises a flat member 4 having a pair of projecting prongs 5 and 6 extending at right angles thereto and substantially midway thereof, and preferably formed by stampingit out of the same sheet metal as that of which the element 4 is made.

The width of the element 4 is greater than the width of the slot 8 so that when the fastening element is positioned this flat member- 1 and 6 fitted between the jaws 8 and 9 of the will engage'the lath 2 on both sides of'the said slot 3 with the prongs projecting through the slot.

In practice to secure the lathingin place against the studding the fastening element is first placed in atool 7 with the prongs 5 tool. f'he jaws of the tool and the prongs are then projected through the slot 3 so that the prongs fit on'each side of the studding 1;

Pressure on the handles of the tool 7 causes the jaw 8 to press the prong 5 into frictional engagement'with the flat side of the studding, while a dog 9a on the jaw ,9 first bends-the prong 6 into substantially the position shown in Fig. 3. This'brings the upper: end of the prong 6 into frictional engagement with the bottom of the channel of the s'tudding as at 6a, and then'with'this point and the'outer corner edge 6?) offhe outer channel leg 1a as fulcrum points, a continued movement of v the j aw 9 of the tool inwardly of the channel causes'the prong 6 to be drawn into the posiform a departure from the spirit of the invention, as set forth herein. Having thus described our invention what we claim as new and useful and desire to secure by Letters Patent is:

The method of securingtogether a stud, a

plaster lath having a longitudinalslet cut therein, and a fastening element consisting of a fiat member having a. pair of prongs projecting therefrom ;."compri "si'ng' 'laying""'the lath against the stud with the slot crossing the stud, moving the prongs through the slot and one on ea'cli'sideof thestud and the flat of thefastening element against the face of the lath, and then applying an instrumentality from the front 'of the lath through the slot to each of the prongsand' pinching them into frictional engagement with'the stud;

In testimony whereof we afiix -our srgiatures. I p

this causes wedgingand drawing action whlch accentuates the propositlon of tightly drawing the lathing, the studding and the fastening elcment into very close frictional engagement, one with the other to insure absolute rigidity of the lathing relativeto the studding after the fastening operation is completed. 7 a

r The same general idea offasteningmetal lathing to the studding is shown in Figs. 6 and 7 but a plain wire clip 10 can be used in this instance, as the flat portion 4 is not necessary in connection with the metal lathing, since the fastening element can'be passed through and around one of the loops of the expanded metal lathing. I

In Fig. 8 we show how one prong ofthe element 10a may be bent behindthe' stud as at 10?) if such fastening is deemed advisable.

From thecforegoing description it will be readily" apparent that we have here' shown and claimed a method and means for accomplishing the fastening of the lathing to studdingin a very simple and efiicient manner, and working only from the front of the wall,

and involving a minimum expense of time,
